"Specification forming part of Letters Patent No. 95,2!0, dated September28, 1869.

To all lwhom Ait may concer/n Beit known that I, CHARLES S. DUNBRAOK, of Swa'inpscott,` of the county of Essex and State of Massachusetts,` have made a new and useful finventionhaving reference to Shoes or Boots; and I do hereby declare the same to be fully described `in the following specilication, and represented in the accompanying drawings; l

Figure 1 denotes a transverse section of a shoe-upper lasted, and `having applied to it and the upper lasted on it `a sole prepared in 'accordance with my invention, Fig. 2 is a top View; Fig. 3a bottom view; and Fig. 4 a transverse section ofa sole as it appears preparatory to being lasted.

`My present invention consists in the outer sole as made with a groove or channel to rc` ceive the upper, such groove or channel bein made in that face of the sole against which the upper is to abut; also, in the outer sole as made with` such a groove in one face, and with astitch-receiving groove in its opposite face, the Whole being substantially as hereinafter described. l y

` `In the drawings, the last is represented at A as recessed in its bottom or sole, as shown at a, to receive a false inner sole, b, ,provided with aseries of spurs, e, extended from it, the whole being as represented and described in the specification and drawings of another application for a pa ent made by me, and to which my present application is auxiliary.

In Fig. 1, B exhibits the upper leather on the opposite side I make Within thesole, and

around it and near its periphery, a groove, e

This groove is to enable the upper to be` drawn into the sole by the sewing extending through-the sole from the other groove, the same Being to prevent the stitches from'being seen or exposed when the upper is drawn up. ward from the outer sole. Furthermore, the groove is advantageous in other respects, or it operates to make a closed joint betweent the outer sole and the upper, and thus renders the sole more impervious to Water.

l. An outer sole as made With the upper receiving groove or channel e, arranged in that face or side of the sole which is to abut against the upper leather to be joined to the so e.

2. An outer sole as made With the Sewing or stitch groove d in its outer face, and With the upper receiving-groove e in `its inner or upper face, such grooves being arranged relatively or opposite to each other, in manner as represented.
